Abstract:

It is shown that at 1700--1800 the cubic carbide of vanadium VC dissolves nearly 10 mol of the hexagonal carbide WC. At 2150--2200 the vanadium carbide VC dissolves more than 50 mol of the tungsten carbide WC, and besides on the VC base a single-phase system will be formed--a continuous row of solid solutions with a smoothly variable period of identity from 4.16 to 4.21 kX along a very steep curve. The period of the identity c lattice of the WC phase decreases by 3--4 units in the third place after the point the a period remains constant as compared with pure WC. This can be explained, probably, by the very small solubility of the cubic VC carbide in the hexagonal WC carbide. Author
